The invention has for an object to effect improvements in advertising devices of the general character in which a series of leaves are turned.

It has for an object to simplify the construction of such apparatus, to the end that manufacturing costs may be reduced, and the device constructed with few and rugged parts liable in a niinium degree to derangement. It is also an important aim to enable the embodiment of the necessary apl0 paratus by utilizing stock materials and apparatus and in its special features conforming to production methods of a simple nature.

It is one salient object to enable the construction of a leaf carrier of a highly satisfactory character utilizing the simplest materials fabricated in an inexpensive manner, and to operate these by a single operating member of extremely simple form.

It is contemplated to enable the setting up of an advertising device in which the entire display assembly may be removed manually by mere lifting thereof, and replaced by another which'by mere manual emplacement will be in proper operative relation to the operating mechanism without requiring delicacy of adjustment or mechanical skill. In this way numerous devices may be placed in operation at scattered locations, the subject matter prepared at a central ofiice where the display units consisting of only the card or leaf holding group or assembly will be made up with desired changes of program, and these prepared units sent to the proper machines by a messenger, who will lift off the old display with one hand and set in place the new set with the other hand. The advantage of this will be well underembodiment of the invention, parts of the casing being broken away.

' There is illustrated an advertising unit including a case 15 having a base plate 16 on which there is bolted the foot flanges of a motor 17, and the foot plate 18 of the turn-table mounting 19. The case includes a slightly inclined front wall 20, slightly higher than the back wall 21. and a top 22, which maybe removable or not aside, sired, and may be in one or more pieces as rquired. In the present instance it stopsshort of the front wall 20 a distance, forming a slot 23 at the extreme front part of the case across the top, and from the front wall 20 a light guard 24 is extended rearwardly and upwardly over the slot 23 as an integral continuation of the front wall and forming a front top of the case. One or more electric lamps 25 are mounted just within'this slot to illuminate the displayed matter whileat observation position; The end walls 26 are shaped suitably to form'junctions with the wall 20, 21, 22 and 24. The mounting 19 is shown as a casting on which a step bearing 27 is formed consisting of a simple cylindrical bore on an axis at a slight angle to the'vertical, ten degrees inclination having been'found satisfactory, although .this'li' may be varied as circumstances may require.

The bored part'is suitably braced by webs from the plate 18. Set removably in the bearing 27 there is a stud.

shaft or pintle 28 on which there is fixed a disc 29, above which the shaft 30 is continued either integrally or by a separable telescopically connected shaft 29 to the top of the leaf holder assembly to be described.

For this purpose the shaft 28 is bored axially at its upper end and formed with longitudinal slots 31 at the extremity, the end of the shaft 30 being slidably inserted in this last named bore and fixed against relative rotation by a pin 32, the ends of which engage in the slots sdtlfat the shaft 30 may be lifted out when desired. {Iiheretainer, if desired. If the sli aft28' is-'ext'ended integrally it will be removable from the stepbearing manually as will be explained; The "ShaftB'O has fixed at its upper extremity 'afdis'c 33 'of-the same diameter as the one 29, and thextw discs have each a concentric series of apertures "34 therein, the openings one disc being alined with those of the other disc. p

This cam con- ;sists of a planiform lobe or sector 54, its periphery concentric with the shaft 47, a lateral projection 6f its radius including the lower end portions and armsl36 of the two shafts 35 at the front medial part 'of tl'i'edi'sc' 29 which is the display or observationipoint or. position.

" I nj as, the applianceb' rig H a I scribed, and I the motor: being Te'rirgiied, "the cam tasis will b rotated to :mb e its top S e forwardly at intervals suitedto the natureof'the'fmattr "displayed; This interval-maybe varied'by subl'stitutin'g a larger ofsrrialler g e'arf48fand shifting the meter to brih gthegearlg into mesntnereshafts 35, pushing it fforwardly, and cjausingthe leaf holder'etf on therespectivefshaft 381thv swing from' it's extreme right handfobservation position forwardly on the, shaft '38 as" apiivot. When [the j arm 36.11215 turned sufficiently 'tojlieparallel with the adjacent portioniof thefhelicoid 55, the helicoid engages the base'portion of'the arm and moves the shaft 35 andturretolocliwise, as viewed from above. The turning-ofthe shaft @35 and shaft 38 on theiraxea'ajlso continues -by the pressure of the cam against the a right handfside ofthe arm 36, and afterthe arm 36"reaches a yposition at th e left of and parallel [to the cam sector 54 the rotation of shafts 35-If8 is continued'by friction of the cam ag'ainstthe right hand side of the shaft 35yas well as by the momentum already imparted to the leaf holder and byimp'act' of-air'against the content of the leaf holder which air has been drawn behind the leaf holder by the initial movement of the content of the holder. Principally, the movement is completed by the action of gravity, due to the rearward inclination of the leaf holder assembly.

If the shafts 35-38 should stick with the leaf holder only partly turned after rotation of the assembly one stage, the spring 58 will press the arm 36 to the left still further causing completion of the movement of the leaf holder.

By forming the shafts 35-38 in one piece, the sleeves 39 may be omitted, and by forming the shafts 28 and in one piece, with'the disc 29 secured to the central shaft as already shown, the entire leaf holder assembly (which may be called a turret or turntable) may be grasped manually at the top disc 33 and lifted from the mounting 19 whether the motor is operating or not, and may again be put in place or replaced by another by a reverse operation, even with the motor operating.

In this way, as before explained, when it is desired to change the program or collection of matter on a machine, a separate turret including the shaft 30, and assembly of shafts 38 and leaf holders thereon may be prepared at a distant pointwith the desired change ofdisplay, and sent by messenger to be substituted as indicated. A route for the messenger may include a multiplicity of widely distributed machines, and the messenger may carry a large collection of turrets to be substituted for those on machines on his route. Advertising agencies and specialists may thus exercise a closer supervision and prompt changes of display.

In Figure 10, a specific embodiment of the turret in which the central shaft parts correspond to the shafts 28*30 are formed as one shaft 60, and instead of the separate elements and 38 forming the pivots of the leaf holders, a single shaft 61 is formed of simple rod stock, having its lower end bent to form the arm 36, in each instance. The lower disc 29 and other construction may be the same as before described. The turret of Figure 10 is interchangeable with that lfand' disc- 29.
